2 claims; (ci. icl- 211) This invention relatesto tobacco pipes and moreparticularly to pipes in which provision is made for cleaning andcooling the smoke before it passes into the smokers mouth.

An important object of the invention is to` provide a novel andadvantageous pipe of the type referred to. Another object of theinvention is to provide novel and `advantageousmeans` whereby the pipebowl and the stem or barrel of the pipe may be readily assembled ortakenA Yvention is to provide a novel form of pipe in which smoke drawnfrom the tobacco chamber of the bowl is passed into an elongated chamberin the stem or barrel and then is drawn from this barrel at a point tothe Vvfront of the connection with the tobacco chamber and thenrearwardly to the mouth piece.

Another.object of the invention is to provide a novel form of pipecomprising a bowl and a stem or barrel extending completely through thebowl, but connected at one side with the tobacco smoking chamber sothat; the barrel can easily be cleaned without removing it from thebowl. A further object is to provide a novel pipe of the characterdescribed which is economical to manufacture, simple in construction andecient in use.

According to a preferred form of the invention the bowl is formed with atobacco chamber having an outlet at the center of the bottom thereofwhich communicates with an opening in the side of a barrel passedcompletely through the bowl beneath the tobacco chamber. The barrel anda mouth piece at one end thereof constitute the stem of the pipe. Theend of the barrel extending through the lower pari; of the bowl, may beclosed in any suitable way as by a plug fitted to the open end of thebarrel. With this arrangement, it is evident that the smoke drawn intothe barrel may be cooled therein while at the same time impurities maysink to the lower side of the barrel, and the cleansed and cooled smokemay be drawn through a smaller bore in the mouth piece into the mouth ofthe smoker. Such cleansing and cooling effects may be promcted by use ofa tube extending longitudinally of the cooling and cleansing chambers inthe barrel and of smaller diameter than the interior of the barrel. Saidtube may t at one end:

into the inner end of the bore through the mouth piece and at itsotherend may be supported in a suitable opening provided in the cap. This 4tube may be provldedwith one or more inlets at such ai location thatlthe smoke after being cooled and cleansed in the barrel proper will then.be drawn towards the plug end. of the barrelV and through said inletsinto the tube through which it passes to the mouth piece. The tubemay beattached to the cap to facilitate removal of the tube. in the barrel.

Other objects,-features, and advantages willA appear upon considerationof the following detailed description and of the drawing in which:

Fig. 1 is a sectional view taken along a plane through the axis of thepipe bowl and theaxis of the pipe stem;

Fig. 2 is a plan View partly broken away, ofVVV the structure shown inFig. 1; n

Fig. 3 is a view partly broken away illustrating certain details of thestructure shown in Figs. `1 and 2.

Fig. 4` is a top plan view of the inner tube shown in Fig. 3; and

Fig. 5 is a View of the structure in Fig. 3 as Viewed from the right.

Referring to the drawing, there is disclosed a pipe in which thev bowlI0 contains a tobacco chamber II terminating at a considerable distanceabove the lower end of the bowl b-ut is connected through a downwardlyextending passage I2 with a hole I3 in the side of a barrel I4 formingpart of a pipe stem passing directly through the lower part of the bowland tting closely therein. This barrel is open at the end which extendsthrough the lower part of the pipe bowl and the other end of the barrelis connected with a mouth piece I5 which may be integral therewith butpreferably is a separate part. In use the open end of the barrel I4remote from the mouth piece may be closed by suitable means such as aplug I6.

The pipe may be smoked without any further provisions for cooling andcleaning than those just described. Preferably, however, provision maybe made of an interior pipe I I of smaller external diameter than thediameter of the cleansing and cooling chamber in the barrel I4. One endof said pipe I'I may be connected to the inner end of the bore I8 of themouth-piece I5 and the other end of the pipe I1 is closed in use andextends into a. bore in the inner end of the plug I6. The pipe Il at aposition farther Overheating may be prevented by vents:

from the mouth piece than the passage I2, that is, to the front of thispassage, is provided with one or more openings I9 through which smokefrom the barrel passes to the interior of the pipe and may be drawnthrough the mouth piece I5. This mouth piece may be open at its outerend in a usual manner. According, however, to the present invention, theouter end of the bore or passage I8 may also open into additional outletpassages, such as passages and 2| which may incline away from saidpassage I8 so as to distribute the smoke as it enters the mouth andthereby avoid concentration which might cause irritation in the mouth ofthe smoker.

The closing of the outer end of tube or pipe II may be effected byflattening the end of the pipe and use of additional sealing means ifrequired. The ilattened end of the pipe may be convenient- 1y connectedto the plug I6 by a pivot 22. Preferably such pivotal connection israther loose to facilitate adjustment between the connected parts.

The specic structureof pipe shown in the drawing has many advantagessome of which will now be discussed. The generally at bottom of thetobacco chamber I I makes it possible to have such chamber ofsubstantial capacity without increasing the depth of the chamber. In thesame way the at bottom of the pipe bowl enables the height of the bowlto be limited and at the same time enables the pipe or the bowl alone toremain upright when placed on a horizontal supporting surface.Furthermore, the passageof the hollow barrel or stem I4 completelythrough the lower part of the bowl not only enables a very strongconnection between the parts but facilitates cleaning as well asassembly and taking apart.

Obviously a very close fit may be obtained by suitably tapering thebarrel and the bore into which it is introduced.

Under certain conditions there may be a tendency for the barrel tobecome overheated. 'Ihis tendency may be overcome by providing one ormore vents 23 in the barrel I4 near the bowl I0.

It should be understood that various changes may be made and certainparts may be used without others without departing from the true spiritand scope of the invention.

What I claim is:

1. A pipe comprising a bowl having a. tobacco chamber and beneath saidchamber a transverse bore extending completely through the bowl andconnected with the tobacco chamber by a passage at the bottom of saidchamber, a pipe stem comprising a mouth piece with a longitudinal bore,and a barrel with a longitudinal chamber connected to the bore of saidmouth piece and open at its opposite end, said barrel tting in 4saidbore in the bowl and having a side opening in direct communication withthe passage at the bottom of the tobacco chamber, means including a plugto close the open end of said barrel. said plug having a recess at itsinner end, and an inner tube in the barrel chamber having an open endconnected to the inner end of the mouth piece bore and a closed endhaving one or more inlets to the front of the connection between thebarrel chamber and the tobacco chamber, said closed end of said tubeextending into said recess, and a pivot for supporting said closed endfrom said plug.' v
